Wi-Fi Range: How Far It Reaches Indoors and Out
Lance Ulanoff brings extensive experience with consumer technology and digital life. His knowledge spans devices, software, and the everyday questions that come with using technology, with a focus on making complicated topics easier to understand.
Quick answer
Wi-Fi reaches about 20–35 meters (65–115 feet) indoors and up to 120–250 meters outdoors. Walls and other objects can cut that range down fast. The frequency band you use also changes how far the signal goes. Newer types like Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6 can reach up to 70 meters indoors in good conditions.
How Far Wi-Fi Actually Reaches
A single Wi-Fi access point reaches about 20 meters (66 feet) indoors in typical conditions. Wi-Fi follows a technical standard called IEEE 802.11, which defines how Wi-Fi works. Outdoors, with fewer obstacles, some access points are rated up to 150 meters (490 feet), though real-world results vary.
Those numbers are starting points, not guarantees. Your actual range depends on which Wi-Fi protocol your router uses. It also depends on the frequency band and what stands between the router and your device.
Range by Wi-Fi Generation
Each Wi-Fi generation has its own approximate indoor and outdoor range. The figures below assume fairly open conditions. Real homes with drywall, furniture, and appliances will see shorter distances.
| Wi-Fi Generation | Standard | Indoor (approx.) | Outdoor (approx.) |
|---|---|---|---|
| 802.11b (legacy) | 802.11b | 35 m (115 ft) | 140 m (460 ft) |
| 802.11g (legacy) | 802.11g | 38 m (125 ft) | 140 m (460 ft) |
| Wi-Fi 4 | 802.11n | 70 m (230 ft) | 250 m (820 ft) |
| Wi-Fi 5 | 802.11ac | 35 m (115 ft) | — |
| Wi-Fi 6 / 6E | 802.11ax | 30 m (98 ft) | 120 m (390 ft) |
Wi-Fi 4 (802.11n) shows the longest indoor reach in this table. It operates on both the 2.4 GHz and 5 GHz bands and uses MIMO antenna technology. MIMO means the router uses multiple antennas at once to send and receive data. Wi-Fi 5 and Wi-Fi 6 operate mainly on the 5 GHz band, and Wi-Fi 6E adds the 6 GHz band. Those higher bands trade range for faster speeds.
Why Frequency Band Shapes Your Range
There is a basic tradeoff with Wi-Fi frequencies. Lower frequencies travel farther and pass through obstacles more easily. Higher frequencies carry more data but lose strength faster.
The 2.4 GHz band — used by older protocols like 802.11b/g and still supported by Wi-Fi 4 and Wi-Fi 6 — penetrates walls and floors better. The 5 GHz band, used by Wi-Fi 5 and Wi-Fi 6, delivers faster speeds at shorter distances. Higher-frequency signals get absorbed more easily by walls and solid objects because of their smaller wavelength. That is why 5 GHz does not travel as far as 2.4 GHz through obstacles. The 6 GHz band (Wi-Fi 6E and Wi-Fi 7) offers very wide, clean channels for high throughput but has the least wall penetration of the three. See 2.4 GHz vs 5 GHz Wi-Fi: range, speed, and which to use for a deeper look at choosing between bands.
What Cuts Range Inside Your Home
Walls, pillars, and home appliances can greatly reduce range, according to Wi-Fi documentation. The effect depends on the material. Drywall causes modest signal loss, while concrete, brick, and metal framing absorb much more. Microwave ovens, cordless phones, and Bluetooth devices can also interfere with the 2.4 GHz band, because they share the same radio spectrum.
This is why two homes with identical routers can have very different coverage. A single-story open-plan house may get full signal across a wide area. A multi-story home with concrete floors might cover much less.
Strong Signal Does Not Mean Fast Internet
One common misunderstanding: full signal bars on your phone do not guarantee fast or reliable internet. Data rates can vary a lot based on distance, obstacles, and interference. You can have a strong Wi-Fi connection and still get slow speeds. That can happen if the router is congested, your ISP connection is slow, or your link rate has dropped. Signal bars measure radio coverage, not your broadband speed, latency, or packet loss. If you think the problem is your ISP, plug a device directly into the router with an Ethernet cable. Then run a speed test. That is the clearest way to tell the two apart. For step-by-step help, see Wi-Fi connection troubleshooting in Windows.
Extending Range Beyond One Router
When a single router cannot cover your space, you can add more access points with overlapping coverage. Coverage from one or more linked access points can range from a few rooms to many square kilometres. Large outdoor deployments use this same idea. For home use, a mesh system places multiple nodes that hand off your connection as you move. A range extender rebroadcasts the existing signal, usually at reduced speed. Mesh Wi-Fi vs. range extender: which fixes dead zones better? walks through the tradeoffs between those two options.
If your speeds are fine near the router but drop in certain rooms, the problem is almost always physical distance or obstacles, not your ISP plan. Try moving the router to a central, elevated spot before adding any new hardware.
Frequently asked questions
Does a Wi-Fi 6 router have better range than a Wi-Fi 5 router?
Not necessarily. The IEEE 802.11 protocol table shows Wi-Fi 6 (802.11ax) at roughly 30 m indoors and Wi-Fi 5 (802.11ac) at 35 m — similar figures. Wi-Fi 6's main gains are efficiency, capacity in dense environments, and speed, not raw range. Both operate primarily on 5 GHz, which limits wall penetration compared to 2.4 GHz.
Can Wi-Fi reach through multiple floors of a house?
It can, but range drops significantly. Concrete and reinforced floors absorb radio signals much more than drywall. A router on the ground floor may reach the second floor but struggle with the third, especially on 5 GHz. Using the 2.4 GHz band or adding a mesh node on the upper floor is the practical fix.
Why does my Wi-Fi slow down at the edge of its range?
As distance increases, the router and your device drop to a lower data rate to keep the connection alive. This is called rate adaptation. The IEEE 802.11 standard notes that rates vary widely based on distance and obstructions. You may still show a connected signal while actual speed has fallen to a fraction of what you get up close.
Does a higher-priced router cover a larger area?
Not always. Router makers often advertise square-footage coverage, but actual range depends on your home's construction, band selection, and antenna design. A mid-range router in an open layout may outperform a premium router in a concrete building. The Wi-Fi generation matters more than price alone.
What is the range of Wi-Fi HaLow compared to standard Wi-Fi?
Wi-Fi HaLow (802.11ah), introduced in 2017, operates in sub-1 GHz spectrum and is designed for IoT devices. The Wi-Fi Alliance states it delivers approximately 1 km range with strong wall penetration — far beyond standard 2.4 or 5 GHz Wi-Fi. However, it is not a replacement for home broadband Wi-Fi; it targets low-power sensors and wearables, not laptops or phones.
